四、扩散大厅的扩散程度和音质有密切的关系,对“空间感”、丰满度、活跃度也有利,并能保持丰满度和明瞭度之间的平衡、语言清晰度和较长混响之间的平衡,还可以保持大厅内音调的自然性。所以在大厅中,扩散和反射声一样应保持各频率之间的平衡。大厅中具有良好的扩散程度可以使反射声分布均匀、消除回声,如图(10)所示。西德伯林“爱乐”音乐厅中 Fourth, the proliferation of diffusion hall and sound quality is closely related to the sense of space, fullness, activity is also beneficial, and can maintain the balance between fullness and clarity, language clarity and longer reverberation Between the balance, but also to maintain the natural tone of the hall. Therefore, in the lobby, diffusion and reflection should be the same balance between the various frequencies. The hall has a good degree of diffusion can make the reflected sound distribution, eliminate echo, as shown in Figure (10). West Berlin “Philharmonic” concert hall
